Description

Technical Field

[0001] This utility model relates to the field of electrical component technology, and in particular to an anti-sway structure for preventing connectors from swaying during welding. Background Technology

[0002] Connectors, including Type-C connectors, USB connectors, HDMI connectors, etc., are increasingly widely used in electronic products such as mobile phones. Connectors are usually fixed to printed circuit boards using wave soldering. Wave soldering refers to spraying molten solder into a solder wave peak as required by the design through an electric pump or electromagnetic pump. The printed circuit board with the connector pre-installed passes through the solder wave peak at a specific angle and with a certain immersion depth, thereby achieving solder joint connection. In this process, the molten solder wave contacts the pads on the PCB and the control terminals of the connector to form a connection.

[0003] Currently, when wave soldering connectors to circuit boards, the control terminals on the connector need to be inserted into the through holes on the circuit board before wave soldering. Since the diameter of the through holes on the circuit board is usually slightly larger than the thickness of the control terminals, the connector is prone to significant oscillation on the circuit board during wave soldering, resulting in reduced soldering accuracy and thus defective products, leading to a high product defect rate. Utility Model Content

[0004] The purpose of this invention is to provide an anti-sway structure that prevents connectors from swaying during welding, thereby preventing large-scale swaying of the connectors and circuit boards during wave soldering, improving welding accuracy, and reducing product defect rate.

[0005] To achieve the above objectives, this utility model provides an anti-sway structure to prevent connector swaying during welding, comprising a connector body and multiple control terminals;

[0006] Multiple control terminals are fixedly connected to the connector body and are located on the side of the connector body respectively; anti-sway components are provided on the control terminals to prevent large-scale swaying when the connector body is soldered to the circuit board.

[0007] The anti-sway structure for preventing connector swaying during welding also includes a first positioning post; the first positioning post is fixedly connected to the connector body and is located on the side of the connector body.

[0008] The anti-sway structure for preventing connector swaying during welding also includes a second positioning post; the second positioning post is fixedly connected to the connector body and is located on the side of the connector body.

[0009] The anti-sway component includes a protrusion; the protrusion is fixedly connected to the control terminal and is located on the side of the control terminal.

[0010] The anti-sway component includes a protrusion; the protrusion is fixedly connected to the control terminal and is located on the side of the control terminal.

[0011] The anti-sway component includes barbs; the barbs are fixedly connected to the control terminal and are located on the side of the control terminal.

[0012] The anti-sway component includes a chamfer; the chamfer is fixedly connected to the control terminal and is located on the side of the control terminal.

[0013] This invention discloses an anti-sway structure to prevent connector swaying during welding. The circuit board to which the connector body is welded has through holes for the control terminals to pass through. During wave soldering of the connector, multiple control terminals on the connector body are inserted into the through holes on the circuit board. The control terminals enter the through holes first, and the anti-sway component then falls into the through holes. Because of the added anti-sway component, the offset of the control terminals within the through holes of the circuit board is limited. This invention utilizes the anti-sway component to prevent large-scale swaying of the connector body and the circuit board during wave soldering, improving welding accuracy and stability, reducing product defect rates, resulting in higher precision products, and reducing friction during use. Because the product is more stable, it can effectively increase the number of insertion and removal cycles during product insertion and removal tests. Attached Figure Description

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] The first embodiment of this application is as follows:

[0024] Please see Figures 1-3 ,in, Figure 1 This is a schematic diagram of the overall structure of the first embodiment of this utility model. Figure 2 This is a structural schematic diagram of the first embodiment of the present invention from another perspective. Figure 3 This is a schematic diagram of the control terminal and anti-sway component of the first embodiment of this utility model.

[0025] This utility model provides an anti-sway structure to prevent connector swaying during welding, including a connector body 101, multiple control terminals 102, a first positioning post 104 and a second positioning post 105; the anti-sway component 103 includes a protrusion 100; the aforementioned solution can prevent large-amplitude swaying of the connector and the circuit board during wave soldering, improve welding accuracy, and reduce product defect rate.

[0026] In this specific embodiment, multiple control terminals 102 are fixedly connected to the connector body 101 and are located on the side of the connector body 101 respectively; the control terminals 102 are provided with anti-sway members 103, which are used to prevent the connector body 101 from swinging significantly when it is soldered to the circuit board. The circuit board to be soldered to the connector body 101 has through holes for the control terminals 102 to pass through. During wave soldering of the connector, multiple control terminals 102 on the connector body 101 are inserted into the through holes on the circuit board. The control terminals 102 enter the through holes first, and the anti-sway member 103 then falls into the through holes. Because of the added anti-sway member 103, the offset of the control terminals 102 in the circuit board through holes can be limited. To better understand this utility model, a specific example is used below: the diameter of the through hole on the circuit board of a certain laptop computer is 0.6mm, and the thickness of the control terminal 102 is 0.25mm. When the control terminal 102 is extremely biased to one side, the... The offset of the connector body 101 will exceed 0.175mm. By installing an anti-sway member 103 with a thickness of 0.1mm on one side of the control terminal 102, the limit offset of the connector body 101 will be improved to 0.075mm, greatly reducing the offset of the connector body 101. Under experimental verification, the control terminal 102 can enter the through hole under pressure under the interference of the anti-sway member 103. This utility model utilizes the anti-sway member 103 to prevent large-scale swaying of the connector body 101 during wave soldering with the circuit board, improving soldering accuracy and stability, reducing the product defect rate, making the produced product more accurate, reducing friction during use, and effectively increasing the number of insertion and removal tests due to the greater product stability. The connector body 101 can be one of a Type-C connector, USB connector, HDMI, etc., and the number of control terminals 102 is designed according to the specific product.

[0027] Secondly, the first positioning post 104 is fixedly connected to the connector body 101 and located on the side of the connector body 101. The circuit board to be soldered to the connector body 101 has positioning holes adapted to the first positioning post 104. During wave soldering of the connector, the first positioning post 104 on the connector body 101 is inserted into the positioning hole on the circuit board to position the connector body 101. The number of the first positioning posts 104 can be set as needed.

[0028] Meanwhile, the second positioning post 105 is fixedly connected to the connector body 101 and located on the side of the connector body 101. The circuit board to be soldered to the connector body 101 has positioning holes adapted to the second positioning post 105. During wave soldering of the connector, the second positioning post 105 on the connector body 101 is inserted into the positioning hole on the circuit board to position the connector body 101. The number of the second positioning posts 105 can be set as needed.

[0029] Additionally, the protrusion 100 is fixedly connected to the control terminal 102 and is located on the side of the control terminal 102. Multiple control terminals 102 on the connector body 101 are inserted into through holes on the circuit board. Because the protrusion 100 is provided on the control terminal 102, during the insertion process, the protrusion 100 slightly protrudes from the control terminal 102. The combined size of the protrusion 100 and the control terminal 102 is slightly larger than the inner diameter of the through hole. Therefore, it is necessary to press the connector body 101 slightly to cause the protrusion 100 to deform slightly and pass through the through hole. After the protrusion 100 has completely passed through the through hole, it will return to its original shape and fit against the lower surface of the circuit board. The protrusion 100 prevents the connector body 101 from wobbling significantly during wave soldering of the circuit board.

[0030] The second embodiment of this application is as follows:

[0031] Based on the first embodiment, please refer to Figure 4 ,in, Figure 4 This is a schematic diagram of the control terminal and anti-sway component of the second embodiment of this utility model.

[0032] This embodiment provides an anti-sway structure to prevent connector swaying during welding. The difference between this embodiment and the first embodiment is that the anti-sway component 103 includes a protrusion 200. The protrusion 200 is fixedly connected to the control terminal 102 and is located on the side of the control terminal 102.

[0033] In this specific embodiment, the protrusions 200 prevent the connector body 101 from swinging significantly during wave soldering with the circuit board.

[0034] The third embodiment of this application is as follows:

[0035] Based on the second embodiment, please refer to Figure 5 ,in, Figure 5 This is a structural schematic diagram of the control terminal and anti-sway component of the third embodiment of this utility model.

[0036] This embodiment provides an anti-sway structure to prevent connector swaying during welding. The difference between this embodiment and the second embodiment is that the anti-sway component 103 includes a barb 300. The barb 300 is fixedly connected to the control terminal 102 and is located on the side of the control terminal 102.

[0037] In this specific embodiment, the barbs 300 prevent the connector body 101 from wobbling significantly during wave soldering with the circuit board.

[0038] The fourth embodiment of this application is as follows:

[0039] Based on the third embodiment, please refer to Figure 6 ,in, Figure 6 This is a structural schematic diagram of the control terminal and anti-sway component of the fourth embodiment of this utility model.

[0040] The anti-sway structure provided in this embodiment to prevent connector swaying during welding differs from the third embodiment in that the anti-sway component 103 includes a chamfer 400; the chamfer 400 is fixedly connected to the control terminal 102 and is located on the side of the control terminal 102.

[0041] In this specific embodiment, the chamfer 400 prevents the connector body 101 from wobbling significantly during wave soldering with the circuit board.

[0042] This utility model discloses an anti-sway structure to prevent connector swaying during welding. The circuit board to be welded to the connector body 101 has through holes for the control terminals 102 to pass through. Simultaneously, the circuit board also has positioning holes adapted to the first positioning post 104 and the second positioning post 105. During wave soldering of the connector, multiple control terminals 102 on the connector body 101 are inserted into the through holes on the circuit board, and the first positioning post 104 and the second positioning post 105 are inserted into the positioning holes on the circuit board. The control terminals 102 enter the through holes first, and the anti-sway component 103 falls into the through holes afterward. Due to the addition of the anti-sway component 103, the offset of the control terminals 102 within the through holes of the circuit board can be limited. To better understand this utility model, a specific example is used below: the diameter of the through hole on the circuit board of a certain laptop computer is 0.6mm, and the thickness of the control terminal 102 is 0.25mm. When the control terminal 102 is deflected to one side, the offset of the connector body 101 will exceed 0.175mm. By installing an anti-sway member 103 with a thickness of 0.1mm on one side of the control terminal 102, the extreme offset of the connector body 101 will be improved to 0.075mm, greatly reducing the offset of the connector body 101. Under experimental verification, the control terminal 102 can enter the through hole under pressure under the interference of the anti-sway member 103. This utility model uses the anti-sway member 103 to prevent the connector body 101 from swinging significantly when wave soldering with the circuit board. The anti-sway member 103 includes, but is not limited to, the form of a convex 100, a convex dot 200, a barb 300, and a chamfer 400, and may also have other equivalent variations. This utility model can improve the soldering accuracy and stability, reduce the product defect rate, make the produced product more accurate, reduce the friction during use, and because the product is more stable, it can effectively increase the number of insertion and removal tests during product insertion and removal. The connector body 101 can be one of a Type-C connector, a USB connector, etc., and the number of control terminals 102 is designed according to the specific product.
